Result | Bowers & Pitsea 2 Takeley 3 |
Competition | Essex Senior League, step 5. |
Hopping | The second match of my day, taking place while Wales were playing England in Cardiff. The crowd of 47 is the club’s lowest of the season and about 33% down on their average. |
This match in one sentence | |
Takeley made the most of their excellent start to the match but were made to work for the win by the home side. | |
So what? | |
Bowers & Pitsea have only one home league win in the calendar year 2011, back in January, and they have two teams below them in the table. They still have to play bottom-placed Clapton once more and have been “concentrating on the league” since last October. Takeley are just below mid-table. | |
The drama unfolds | |
Takeley took the lead early on. Two shots were blocked in quick succession but the ball eventually dropped for Eubell, wearing 9, and he buried it. 0-1. A few minutes later, the home ‘keeper Bastin made a decent save but the ball came out to a Takeley forward, who buried it. 0-2. To be honest, I didn’t manage to identify the goalscorer from the other end of the pitch. I hope it was someone different and I haven't missed a hat-trick. The first two clips, one from each end of the ground, capture the general atmosphere. However, Bowers & Pitsea gradually got themselves back in the game and scored after 40 minutes through Richard Robinson to reduce the deficit. 1-2 at half-time. The home side came out with the momentum for the second half but it took an unusual goal to bring them level. A disputed direct freekick was scuffed low across the six-yard box by Craig Gillam, and perhaps distracted by inrushing attackers, the goalie Cookman somehow found it nestling in the corner of the net to mild surprise all round. 2-2. Having worked hard to draw level, Bowers & Pitsea then rather charitably handed the lead back to Takeley. Eubell seemed to have an age as he went through the middle, got the ball down, and finished. 2-3. The other two clips show the home sides search for the equaliser. A couple of times they went close, and sometimes more composure from #11 Charlie Kirby would have helped, but in the end Takeley held on comfortably enough for the win. Final score 2-3. | |

Go and defuse a bomb in the Wat Tyler Country Park. This is one of the exhibits at the museum. The country park is on land that once had an ammunitions factory, and it now has multiple uses. In fact you could get married, study the molecular structure of nitroglycerin and learn about tower-block demolition on the same day. | |
A snippet from the programme | |
Something random | |
I was approached by a supporter who wanted to say hello and shake my hand. As I must have looked bemused, he decided to clarify whether I was indeed the manager of Hullbridge Sports, and was rather disappointed when I was not. Apparently I am his double, so a trip to this Essex Senior League club will be needed sooner rather than later to check this out. Anyone got a pic? | |
What Next? | |
I shall look out for a chance to get to either FA Vase semi-final second leg next Saturday (at King’s Lynn or Whitley Bay, though I am not optimistic about getting a ticket), and in the meantime there will probably be a local midweek hop on Tuesday. |

Date & Venue | Saturday 19 March 2011 at Vale Farm (Wembley FC) |
Result | Hendon 2 Margate 3 |
Competition | Isthmian Premier League (step 3) |
Hopping | This does not add to my lifetime total as I was here earlier this season to watch Wembley FC. However, it was good to cross paths again with one of my first non-league Twitter friends, Margate supporter @JeremyJacobs. |
This match in one sentence | |
Margate went in at half-time on their way to a comfortable win against ten men, until a crazy second half of red cards and penalties left them with nine men hanging on for the win. | |
So what? | |
Margate stay 14th and Hendon drop one place to 16th (4pts behind with two games in hand) but both clubs look safe to stay in step 3 next season. Margate are looking for a new manager having parted company with Iain O’Connell this week. | |
The drama unfolds | |
Managerless Margate made a bright start and Craig Cloke scored with a header after 8 minutes. 0-1. After 15 minutes, another defensive lapse allowed Tom Bradbrook to shrug off the last defender and finish neatly. 0-2. It really did look game over at that point, especially when Hendon’s Danny Dyer was sent off with a straight red card on 23 minutes for a tackle that was deemed dangerous by the referee. The rest of the first half was unremarkable and we anticipated a second-half doze in the sun. The first clip captures the general ambience. 0-2 at half-time. How wrong we were. Hendon came out with purpose and soon got a goal back with a move that scythed through the middle of the Margate back four. Belal Aite-Ouakrim was the scorer, after 52 minutes. 1-2. They were soon level, six minutes later. Margate full-back Tommy Osborne diverted a goalbound attempt with an obvious handball on the line, and was duly red-carded. The second clip is of the resulting penalty, taken by Jamie Busby. So, 2-2 and 10 v 10, all to play for after all with half-an-hour left. Then Hendon keeper Berkley Laurencin came out of his area, missed the ball but forced James Pinnock wide. As the keeper raced back towards the byline, he brought down Pinnock who was about to roll the ball across the unguarded goalmouth towards onrushing team-mates. Penalty? Definitely – but what colour of card? The third clip tells the story. Now, 2-3 after that penalty from Wayne Wilson, and almost 2-4 as the ball was rolled beautifully from the wing by Bradbrook into wide open central spaces for Pinnock to hit it first time on the run, but Laurencin made a good diving save. Another missed tackle, and a yellow for Pinnock, meant that Hendon’s Busby had the chance to equalise from the spot. The clip shows what happened and caught a prophetic moment from another guest Margate supporter, Neil, with whom I was chatting. Neil showed early signs of conversion to non-league fandom, which is excellent. A great save from Jamie Turner in the Margate goal preserved the lead. When James Rogers earned a second yellow (and therefore a red) to send Margate down to nine men, we were in for a frantic finish. Busby hit the post with a long-range shot with Turner beaten, but Margate played a 7-1 formation, more or less, and held out for the win with Shaun Welford working his proverbial socks off as a target man. Final score 2-3. Hendon will rue their sluggish start to the game, and Margate's new manager will have some work to do. | |

The goalscoring pattern is the same as the classic FA Cup final from 1978-9, where Arsenal were coasting at 2-0 at half-time, Manchester United got back to 2-2, but Arsenal got a late winner. | |
A snippet from the programme | |
Former Hendon midfielder, now playing for Chelmsford City, Takumi Ake, emotionally recalled seeing the devastating scenes of an earthquake and tsunami impact upon his home country for the first time as “like something out of a film”. But he expressed his thanks for the recent contributions to his “Tako Fund” to raise cash for the British Red Cross’ relief efforts. The diminutive wide man was upset by the tragedy at home, fearing for the safety of his relatives. He said: “My family and friends are all fine, though at first I was a bit panicky until I spoke to them about four hours after I heard the news … When I saw it all I just couldn’t believe it – that’s actually happening in Japan. That’s something you see in a film and I was in shock.” | |

Work commitments will prevent a Tuesday hop this week, sadly, so no definite plans as yet. Look out on Twitter as I may give you a chance to choose somewhere for me! |

Embrace the Numbers - Quarter-Final Draws
In interviewing scores of people for jobs in schools over the years, I have met many people who were quite happy to admit they felt uncomfortable with numbers, and mathematics in general. My aim in this particular post is to explain some probability calculations in an accessible and readable way, and try to demystify some of the supposed difficulty. You might want to have a calculator to hand, and you might want to come back and read it again. You might want to run screaming into the night in the general direction of Hertfordshire with a lump mallet and intent, but I hope not.
On Thursday I asked: "What are the chances of Man Utd playing Tottenham AND Real Madrid playing Barcelona in the Champions League Quarter-Final draw?" (Doesn't matter which team is at home in the first leg.)
The classic quarter-final draw has eight balls in one pot, which can be drawn out with no special seedings or restrictions, to give four ties, with home & away teams decided by the order of the draw. The mathematics is exactly the same for the current Champions League quarter final draw and the Sixth Round of the FA Cup or the FA Vase.
We have just learned that this year’s CL QF ties are Inter/Schalke, Real Madrid/Spurs, Barca/Shaktar & Chelsea/Man Utd. I tweeted that the chances of this happening were 0.059523809%, and hopefully this post will prove it in a way that is relatively easy to understand, and also give the answer to the above “competition” which I set in the previous post from the Haringey Borough game.
Step One – How many alternative draws are there?
Imagine the balls are numbered 1 to 8. They could emerge in the order 4>3>7>1>8>5>2>6 but this is only one of many possibilities.
To establish the pattern, let’s simplify things and consider a draw of only two teams. There are TWO possibilities for the first ball out, 1 or 2. However, whichever one comes out, there is only ONE ball left in the bag. So the only possible sequences are 1>2 or 2>1 and a total of 2 x 1 = 2 possibilities.
For three balls in a bag, there are THREE different possibilities for the first ball out. For EACH of these outcomes, there are TWO different possibilities for the second one out, and then the third is fixed because there is only ONE left. This means 3 x 2 x 1 = 6 possibilities. They are 123, 132, 213, 231, 312 and 321. (This pattern does not appear in cup draws as there are an odd number of teams!)
Four balls in a bag is a classic semi-final draw, and I have covered this in a previous post. Hopefully it is clear by the same logic that there are 4 x 3 x 2 x 1 = 24 possibilities, and the table in the post covers them all for the conspiracy theorists.
These numbers are known as factorial numbers and denoted by the ! symbol in conventional mathematical notation. 1! = 1, 2! = 2, 3! = 6 and 4! =24. So the first number that we need for our quarter-final analysis is 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320. In other words, the sequence 43718526 that I mentioned above is only one of 40320 unique possibilities for the appearance of the balls.
(We will need to remember later that some of the different sequences have the same sporting outcome in our particular example. If the teams appear in the order 12345678 then the matches will be the same as if they appear 78563412. More of this later.)
(These numbers get pretty large in the earlier rounds of the competition. Try working out the number of possible draws for the third round of the FA Cup, which has 64 teams! It's about one hundred and twenty-seven thousand billion billion billion billion billion billion billion, using a billion to mean a million million. Perhaps we'll come back to this next January, if you are still speaking to me.)
Step Two – What is the chance that Man Utd will play Tottenham?
In my question, I made no distinction about which team was home or away on the first leg, so common sense takes us the next step. Assuming the draw is fair, Tottenham is one of seven possible opponents for Manchester United. All of these opponents are equally likely, so the chance of any named one is 1 in 7 (expressed as betting odds), one seventh (expressed as a fraction of one) or 14.2857% (expressed as an approximate percentage chance). You can see this by working out 100 divided by 7 on a calculator, and it is an example of a recurring infinite decimal. One seventh is 0.142857142857142857…. with the six numbers repeating in the same order.
Putting this visually, the size of this rectangle represents all the possible 40320 draw outcomes. The reason why this is a 5x7 grid will become clear shortly.
In one-seventh of these (5760 of them to be precise), Manchester United will play Tottenham. In another 5760 of them, Manchester United will play Real Madrid. Manchester United have to play someone, and 7 x 5760 = 40320 as all seven opponents are equally likely as we said.
So the green-shaded area represents the 5760 possible draws in which Manchester United would play Tottenham, and the other six teams are playing each other in all the various permutations.
Step Three
What is the chance that Man Utd will play Tottenham AND Real Madrid will play Barcelona?
For the second part of my competition question, we have to focus ONLY on these 5760 possible draws that put Manchester United and Tottenham together. Real Madrid may play Barcelona in lots of possible draws in which, say, Manchester United played Shaktar and Tottenham played Inter. Those would be irrelevant to the question, which is about the chance of two things happening simultaneously. To mathematicians, the word AND is very different from the word OR in these types of problem.
So let’s assume that Manchester United are to play Tottenham, in one of those 5760 possibilities shaded in green. Real Madrid must be playing one of five other opponents, equally likely. So one-fifth of those 5760 outcomes will have Man Utd v Tottenham AND Real Madrid v Barca. 5760 divided by 5 is 1152. In other words, 1152 of the 40320 possible draws will have these two pairings. (The other two pairings could be either way round, it wouldn’t affect the answer to our question.)
Visually …
The dark-blue segment represents our answer in which Man Utd play Tottenham AND Real Madrid play Barca. It is one-thirtyfifth of the whole rectangle.
So we have two ways to calculate the final answer.
The fraction one-thirtyfifth as a percentage is worked out by pressing 100 divided by 35 on a calculator and we see 2.85714%. Again, those numbers would repeat in an infinite decimal. The same answer is achieved by calculating the odds as 1152 divided by 43020 and multiplied by 100 to get a percentage. 2.85714% again – it’s really exactly the same destination, just reached by two different routes.
The winner was: Hitchin-based tweeter @novice2scratch who is having an interesting sporting life of his own, which I hope you will all now follow immediately on http://novice2scratch.com/. There's a great story unfolding there. For the record, he supplied the correct answer within minutes of seeing the question.
Step Four – Finally, why did the real draw have a 0.059523809% chance of happening?
Remember that there are 40320 unique draws – each one is a unique sequence of the eight balls. The chance of any individual sequence, say 14528763, is 1 in 40320 (expressed as odds), 1/40320 (as a fraction) and 0.00248015873% as a percentage. If you try 100 divided 40320 on your calculator it will either round it to something like 0.00248 or will show it in something called standard form as 2.48015873 x 10-3. I’m guessing that if that means anything to you, you have easily understood the rest of this post so I am moving on quickly. It’s a small chance – one in about forty thousand.
However, in this particular context it doesn’t really matter to us which order the four ties come out. Remember I said earlier that we would need to come back to this point. With four ties to be drawn, there are 24 possible ways of getting the same sporting pairs with the same home/away order (by the same logic as the semi final draws), so my final step is to say that this combination of teams in the right home/away order would have come up from 24 out of the 40320 possible outcomes, and the same type of calculation gives us 0.059523809%. 24 divided by 40320 multiplied by 100 if you want to check.
Remember, you will be able to say, “Well, that had a 0.059523809% chance of happening!” EVERY year after EVERY FA Cup Round Six draw. The numbers will always be the same, and if that doesn’t win you gasps of admiration I’ll be amazed.
Postscript – What were the chances of an all-English tie?
There are three English teams in the draw, so there could be one all-English tie, or none. Going back to our visualisation, the green area represents all the possible 5760 outcomes in which Man Utd play Tottenham. Chelsea could be playing any one of the other five teams. The orange area represents all of those (another 5760) in which Man Utd play Chelsea, and Tottenham could be playing any one of the other five. The purple area is for Tottenham playing Chelsea.
We can see that as a fraction this is three-sevenths, or (3 x 5760) out of 40320 = 17280 / 40320. Either route leads us to 42.8571% and those same digits in a different order! Beautiful, I think you'll agree.
So there we are. Welcome to my world. I told you there'd be tangents, and remember, "Chance is a Fine Thing". :)
